This Mila Barratt Homes multipoint door lock features 2 Rollers 2 Hooks & 1 Latch.
Mila Barratt Homes multipoint door locks were very widely fitted to new build homes until the mid 2000's. While this classic lock is not part of Mila's current range of UPVC door locks, they are still available, manufactured by the same factory that originally made them in Italy. The Barratt Homes UPVC door lock is commonly found fitted to the leading leaf of a pair of balcony doors.
Identifying a Barratt Homes UPVC door lock is easy once the lock is out of the door. The shape of the gearbox is very distinctive, featuring triangular corners. Identifying the lock before it has been removed can be a little more tricky as these locks were rebranded by a number of different door and window companies. The lock may be stamped Mila, but could also have Barratt on the faceplate. Regardless of the branding, they are all the same lock underneath.
The Barratt lock features a unique 2 hook and 2 roller configuration with no central deadbolt (only a latch). The distance between the top hook and spindle is only 355mm, making it ideal for use on balcony doors, which are normally lower height.
Mila Barratt Homes gearboxes are available in latch only configuration, with a single spindle. They are available in 25mm, 28mm and 35mm backsets.
Despite the various backsets and operation options, the dimensions of Mila gearboxes are largely the same. They measure 233mm high by the backset + 20mm wide. The latch measures 20mm high, the deadbolt is 30mm high and there is 80mm between the bottom of the latch and the top of the deadbolt.
Please note that some older locks feature an offset, or cranked connector. This is only an issue when replacing a gearbox, rather than a full length lock, but its an important point to consider. Replacement gearboxes are now only available with inline connectors. They are still compatible with older locks but it will be necessary to adapt the drive gear that runs behind the faceplate. Follow our technical guide on the process, but there is a square hole in the drive gear which needs to be cut to create a slot to ensure that the lock works.
Barratt hooks are bi-directional, with the top hook moving downwards, and the bottom hook moving upwards in each pair of hooks. Hook cases measure 95mm high by 45mm wide, making them one of the smaller hook cases on the market. If the door routing is tight, this can require work to allow a replacement hook lock to fit.
Rollers are used for compression, to pull the door against the frame, to help prevent dust or water ingress. They do little for security, but they also have the added benefit of helping to prevent the door from becoming warped as it is supported across its full height. This is dependent on the rollers being engaged into their keeps.
Rollers are normally adjustable by 1mm to help achieve optimum weather sealing.
